Installation, disassembly, repairs and maintenance of the VIGIA Tire
Pressure Systems must be performed only by a certified mechanic
with specific knowledge in the installation of VIGIA Systems.
Certified mechanic must use proper protective equipment when
installing, repairing and maintaining the VIGIA systems.
Improper installation or use of unauthorized parts can cause
malfunctions, loss of tire pressure and other consequences which
may result in serious injury or death.
Manufacturer or Distributor will not be responsible for injuries
resulting from misuse of equipment, use contrary to operating
instructions or installation by any person other than an Authorized
Installer.

VIGIA AUTOMATIC TIRE PRESSURE SYSTEM
VIGIA constantly checks and maintains tire pressures at a constant,
pre-set level while providing instant, ongoing feedback to the driver.
VIGIA delivers increased tire mileage, less down time, better fuel
economy and increased safety.
Operation
In the event of a drop in pressure in one or more tires due to punctures or
other causes, the system automatically generates signals that inform the
driver of the problem and its location. At the same time, the system
begins pumping air, keeping tire pressures calibrated at the pre-set
levels.
If the loss of air is substantial, as in the case of a blow-out, and the
equipment is not able to compensate for this loss, a signal advises the
driver. At the same time, an electronic security valve blocks any air to the
tires, thus ensuring the normal operation of the other air-operated
systems (i.e. brakes, suspension, etc.).
Model NM244 is a stand-alone external system for trailers.
Model NM253 is a dedicated external system for trailers and requires a
tractor equipped with VIGIA System.

Operation
Green L.E.D. Only :
Normal Operation.
Tires are calibrated.
Yellow L.E.D. (flashing):
Tire punctured or
air leak. The system is recuperating the air
loss and driver can continue the trip.
3
Yellow L.E.D. (solid): The system is unable
to maintain the set pressure. Stop the vehicle
and with the engine running allow the system
to recuperate pressure. Check the problem.
Red and Yellow L.E.D.s (alternating):
Excessive air loss and low air tank pressure.
Automatic system disconnection (system
will reconnect automatically when air tank
reaches its normal pressure). Driver to safely
stop the vehicle and check the problem.
To quickly trace an air leak ( yellow LED on), turn the system off and:
a) If the gauge reading falls quickly, the leak is located in the system network
between the VIGIA tire valve and the control module.
b) If the gauge reading falls very slowly, the leak is located in the tire
(puncture) or a VIGIA tire valve is defective or loosely attached to the tire
stem.
IMPORTANT: Tire punctures and air leaks must be repaired as soon as
possible.
Tire Pressure and Temperature
Calibrate with “COOL” tires
OFAMBIENT
16
Tires should be calibrated when they are cool (at ambient
temperature) according to the “inflation table” supplied by
the tire manufacturer.
4
TEMPERATURE
Never bleed tires to reduce increased air pressure due to
rolling resistance
It is normal and expected that tires increase up to 12% psi over the set
pressure when the tires warm up after rolling. This situation is normal
and will be shown by the VIGIA Automatic Tire Pressure System.
Do not deflate the tires to compensate for this increase.
Note: Air pressures may not be the same in all the tires.
When checking tore pressure through the shredded valve, it will
show the pressure of the least inflated tire in the trailer.
If during operation tire pressures increase more than 18% over the set
pressure, the cause should be inspected. Possible causes:
A- Tire over-inflated at the time of installation.
Note: The VIGIA system will not deflate tires.
B- Bad load distribution.
C- Wrong selection of tire size.
D- Different or mix-matched tires on the
Same axle.
5
E- Axles are out of alignment.
F- Different tire sizes in duals.
G- Problems in the vehicle suspension,
steering or alignment.
H- Problems in the brakes.
I-
Incorrect separation among dual tires.
J- Bad or oval wheels.
VIGIA allows you to monitor over-inflation. While the system does not
contribute to over-inflation, it will alert the driver of problems that would
otherwise go unnoticed.

TRACTOR - TRAILER CONNECTION
NM253 ONLY
Connect the valve located at the end of the spiral hose to the fixed valve
located in the trailer.
To unhook, disconnect the spiral hose and protect both valve ends
using the cap and support.
7
SYSTEM MAINTENANCE
Air Tanks and Air Filter - Model NM244
A- The air filter will only retain solid impurities.
To avoid water or other liquids in the system,
drain air tanks periodically.
B- The air filter must be kept clean for proper
system operation. Purge the air filter at least
once a year.
VIGIA Tire Valves
VIGIA’s tire valves incorporate check valves that replace the original tire
valve cores. If air leaks from the tire upon disconnecting a VIGIA tire
valve from the rotor, proceed as follows:
A- Remove the hose and tire valve.
B- Spray the tire valve end with soapy water and make sure that the
valve’s O-ring is intact.
C- Reinstall the hose and tire valve, tightening
lightly with a wrench. Verify that the hose
and tire valve does not rub against wheel
rim, rotor support or hub.
D- If air leak persists, replace hose and tire
valve.

Tire Changes
A- Remove the rotor cover. Disconnect the hose/s at the rotor.
B- Remove the tire taking care of not damaging the rotor.
C- Remove the VIGIA hoses and tire valves and install them in the new
tire according to the following instructions:
- Thoroughly clean the external thread of the
original tire stem with a brush.
-
Remove the valve core.
Screw the VIGIA tire valve, lightly tightening it with a wrench. Verify that the
VIGIA hose and tire valve does not rub against the wheel rim, hub or rotor
support. Modify the valve position if necessary.
D- Ensure that the tire pressure is lower
than the desired tire pressure. The
system will calibrate it to the pre-set
value.
E- Install the new tire.
F- Reconnect the end hose connectors
to the rotor.
G- Reinstall the rotor cover and
tighten its nut.

System Disconnection
Partial
In case of air loss in the VIGIA system, where
no repair is possible at
the moment, the damaged line can be
annulated with the plug provided.
Total
If the air loss is in a place that does not allow
for the partial disconnection explained before,
disconnect the complete VIGIA system using
the ON-OFF switch. Contact your authorized
Vigia service.

IMPORTANCE OF TIRE PRESSURE
Proper inflation is the most important requirement for maximum tire
safety and tire mileage
Low Tire Pressure:
Under inflation increases flexing of the
casing which generates excessive heat
causing fatigue, premature shoulder
wear, cap separation and ultimately
tire failure .
Excessive Tire Pressure:
Over inflation weakens the tire by
preventing the tire to absorb impacts,
generating irregular wear, reducing
resistance to punctures and ultimately
producing tire failure. Over inflation
reduces the area of the tire in contact
with the ground reducing traction and
making the tire skid .
Important: According to tire manufacturers’ specifications, tire pressure
must be calibrated when tires are COLD (allow the tires to cool for 3-4
hours after use). Tire pressure may increase up to 12 % over the “cold”
pressure due to rolling resistance when in use. VIGIA will show this pressure increase in the control panel’s gauges. DO NOT BLEED THE TIRES.
12
RECOMMENDATIONS FROM VIGIA
A- Each time a tire is replaced, make sure that its pressure is lower
than the system’s set pressure.
The system only supplies air to
the tires; VIGIA will not reduce tire pressure.
B- Check that rotors are centered in respect to the wheel every time a
wheel or hub is dismounted.
C- Verify that hose and tire valves do not rub against wheel rims, rotor
supports or hub. Tighten valves securely with a wrench.
D- Replace or repair damaged tires as soon as possible.
